Car battery with stripped threads in female connection for bolt entry.

It's nearly new and cost a small fortune; is there any way to save this
battery?

Checked at Lowes, Canadian Tire and NAPA; the only advice anyone had was to
put a larger bolt on and "force" it to thread into the lead. That doesn't
sound very reasonable to me.

For the time being I've slipped some solder around the threads to take up
space and it let the bolt tighten into the battery firmly, but since solder
has no "memory" (will squash and not apply any pressure eventually) I don't
think it's a very reliable "fix".

Any better suggestions?
